One day a couple of sister missionaries in my district ran out of water and they didn’t want to go buy more water because it was Sunday. So they decided to fill a pitcher up with gasoline and prayed that the gas would be changed into water.
After they prayed, they smelled it and it didn’t smell quite as strong as it had before, so they drank it.
But it turns out that they only had enough faith to turn half of the gas into water.
And one of the sisters had to get her stomach pumped.
